Using Old-Mode Authentication
By default, the IOS uses AAA old-mode authentication. Under AAA
old-mode, each dedicated and virtual line interface that requires
authentication must be configured using the login command. Here is
an example:
local-AS#config t
Enter configuration commands, one per line. End with CNTL/Z.
local-AS(config)#line vty 0 4
local-AS(config-line)#login ?
local Local password checking
tacacs Use tacacs server for password checking
local-AS(config-line)#login local
local-AS(config-line)#exit
local-AS(config)^Z
local-AS#
In the example above, you set up old-mode authentication on the VT
ports on the router. You now need to create user accounts for each
user who requires VT access to the router. This is the same process
you used to create user accounts for the WidgetCo dial-in solution:
local-AS#config t
Enter configuration commands, one per line. End with CNTL/Z.
local-AS(config)#username admin password apassword
local-AS(config)#^Z
local-AS#
After the username is created, you can log in to the router using
old-mode authentication:
